Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544150, here are decompositions:
- 19 + 31544131 = 31544150
- 61 + 31544089 = 31544150
- 73 + 31544077 = 31544150
- 97 + 31544053 = 31544150
- 109 + 31544041 = 31544150
- 139 + 31544011 = 31544150
- 163 + 31543987 = 31544150
- 223 + 31543927 = 31544150
Showing the first eight; more decompositions exist.
